(CNN) – The Republican divide over whether to shut down the federal government in a bid to end President Barack Obama's health care law is merely a tactical split, rather than a larger ideological rift, the party's national chairman said Sunday.

Republican National Committee chairman Reince Priebus, speaking on CNN's "State of the Union," said he wasn't picking a side on the issue, which has pitted establishment party members against their younger colleagues.

(CNN) – Republican National Committee Chairman Reince Priebus said Sunday that his organization’s planned debate boycott was focused on NBC and CNN – which plan to air films about Hillary Clinton – and not companies which may produce those projects.

Priebus, speaking on CNN’s “State of the Union,” was responding to a question from Chief Political Correspondent Candy Crowley about a report in The New York Times that Fox Television Studios was in the “early stages” of talks to produce NBC’s miniseries about Clinton, set to star Diane Lane. Fox Television Studios is a corporate sibling of Fox News Channel and the Fox broadcast network.
